Our educational philosophy is to guide and empower students in the study, understanding, and mastery of computer science fundamentals. We emphasize the transmission of efficient mental models of computer science, software engineering, and coding theories and practices to effect an enduring personal and professional journey of success. We respect and appreciate both the “how” and “why” in our coding experience; “how” addresses the mechanics of coding execution, while “why” addresses the underlying critical reasons for methodological decisions. We view the student-instructor relationship as inspirational and encouraging so as to ignite the student’s unrestricted interests in all knowledge domains of computer programming. The best assessment of your learning progress is your own honest self-assessment of who you are and where you are in your dare to dream a better you and world.
